Pergola vs. Gazebo: Differences and Costs

The difference is the roof. A pergola is posts and beams topped with open slats that filter sunlight, while a gazebo is a freestanding structure with a solid roof that keeps off rain and full sun. For the same footprint, a built gazebo costs more: HomeAdvisor's pergola guide puts pro installation at $30–$60 per square foot, and its gazebo guide cites $75–$100.

Pergola vs. gazebo at a glance

Cost figures are national ranges from HomeAdvisor and vary by region, material and site. HomeAdvisor's overall ranges cover many sizes and materials, which is why its gazebo range runs lower than its 10x10 figure. Compare by size when you can.

How a pergola works

A pergola frames an outdoor space without enclosing it. The posts carry beams, the beams carry rafters, and the slats on top break up the sun. HomeAdvisor notes that the slatted roof lets partial sunlight through, which is the whole point: you get a defined "room" over a patio or deck while still feeling outside.

Pergolas are flexible. You can grow vines over the top for more shade, add a retractable canopy (some kits include one), or attach one side to the house over a back door. Because the structure is simple, kits are popular with DIYers. HomeAdvisor says prefab kits take about 1–4 hours to assemble and custom designs about 8–16 hours. Groundwork like leveling or pouring a slab can stretch the job to several weeks.

The trade-off is weather. A plain pergola won't keep you dry, and the shade moves as the sun does. If you want to sit out in a summer shower, you'll need a solid cover, and at that point you're paying for much of what a gazebo gives you.

How a gazebo works

A gazebo is a small, freestanding building with open or screened sides. The solid roof gives full shade and rain protection, and most permanent gazebos sit on a concrete slab or their own raised floor. That makes a gazebo a better destination spot out in the yard, while a pergola usually extends a patio or deck that's already there.

Shape affects price. In ranges that span many sizes, HomeAdvisor lists round or oval gazebos at $1,500–$8,000, square or rectangular ones at $2,000–$12,000 and octagons at $3,500–$8,000. Add-ons are where budgets grow: a basic screen kit is $500–$800, an electrical outlet $180–$500 and gazebo lighting $2,000–$6,000.

What each one costs

Pergola costs

HomeAdvisor puts professional pergola installation at $30–$60 per square foot, with materials making up about 80% of the budget. LawnLove's pergola guide is close: $2,100–$6,000 for a pro-installed pergola, or $20–$60 per square foot with an average near $37.

HomeAdvisor prices most materials for a 100 sq ft pergola, so its figures are shown here divided by 100. Its material prices can come in under its $30–$60 installed rate, so use the installed rate for a full pro-built budget. DIY kits run $600–$7,500 or more, and HomeAdvisor says labor alone usually adds $500–$1,000.

Gazebo costs

Gazebos cost more per square foot because you're building a roof and often a floor. HomeAdvisor cites $75–$100 per square foot for built gazebos. LawnLove's figures point the same way, with an average gazebo near $7,590 versus about $4,000 for a pergola.

By material (again across sizes), HomeAdvisor lists vinyl at $2,000–$3,500, wood at $4,000–$7,000 and metal at $3,000–$8,500. A custom build adds roughly $5,000–$11,000 over a kit. If you need a floor, a concrete slab runs about $4–$8 per square foot and pavers about $10–$17. Our paver patio cost guide covers that part in more detail.

Which one fits your yard and climate

Think about how you'll use the space and what your weather throws at it.

• Hot, sunny regions (Southwest, Texas, Florida): A pergola cuts glare but won't stop midday heat on its own. Plan on vines, shade cloth or a canopy, or choose a gazebo if you want full shade.
• Rainy regions (Pacific Northwest, Southeast): A gazebo lets you use the space in light rain. A pergola needs a solid cover to do the same.
• Snow country (Northeast, Upper Midwest, mountains): Ask the builder or kit maker whether a solid roof is rated for your area's snow load, and how it's anchored.
• Coastal and high-wind areas: Ask how the posts are anchored to footings or the slab. A kit set on loose pavers is not the same as one bolted to concrete.

Material matters too. Wood looks natural but needs periodic stain or sealer, while vinyl and aluminum need little more than washing.

Placement is the other big factor. A pergola works best right off the house over a patio or deck, where it extends the space you already use. If you're still deciding what goes underneath, see deck vs. patio.

A gazebo can sit farther out in the yard as a destination. That also means running power or a path out to it.

Pergolas are a natural frame for an outdoor kitchen. Our outdoor kitchen cost guide breaks down what that adds, and our landscape lighting guide covers lighting either structure.

Permits, HOAs and digging

Permit rules depend on your city or county. Many jurisdictions use the International Residential Code, which exempts one-story detached accessory structures up to 200 square feet from a building permit, as shown in Federal Way, Washington's summary of IRC R105.2. That exemption doesn't cover a pergola attached to your house, and local codes can be stricter, so call your building department before you buy.

A few other checks:

• Zoning and HOA rules. Even when no building permit is needed, setbacks from property lines, height limits and HOA design rules can still apply. Get HOA approval in writing before you order materials.
• Permit fees. These vary by city. HomeAdvisor's gazebo guide says fees can run up to about $150, so check your local fee schedule.
• Call 811 before digging footings. Post holes count as digging. The 811 service is free and asks you to contact it a few business days before you start, so buried utility lines get marked.
• Electrical work. Outlets, fans or lights in a gazebo or pergola mean new wiring. Hire a licensed electrician and pull the permit your area requires.

When to call a pro

A small pergola kit on an existing patio is a realistic weekend DIY job. Hire a pro if you're attaching a pergola to the house, building a gazebo with a solid roof, pouring footings or a slab, or adding power.

Before you hire:

• Get 2–3 written quotes for the same size, material and roof type.
• Ask for photos of similar pergolas or gazebos the company has built.
• Check licensing and insurance where your state requires it, and ask who pulls the permit.
• Get the full scope (footings, floor, finish, cleanup) and the payment schedule in writing.
